system.perspective.alterLogging

This function is used in Python Scripting.

Description

Changes Perspective Session logging attributes and levels. All parameters are optional, with the caveat that at least one of them needs to be used.

caution

For the system.perspective.alterLogging function to work, the following line needs to be added to the ignition.conf file, and the Gateway restarted. "X" is the next number in the Java Additional Parameters list in the ignition.conf file. Warning, this will open potential security holes in the Gateway, and is not advised.

wrapper.java.additional.X=-Dperspective.enable-client-logging=true
Example
# Java Additional Parameters
wrapper.java.additional.1=-Ddata.dir=data
